Imingcele yezobuchwepheshe

I-1,3-Butadiene iyinhlanganisela ephilayo enefomula yamakhemikhali ye-C4H6. Kuyigesi engenambala enephunga elincane elimnandi futhi kulula ukuyincibilika. Ayinabuthi obuncane futhi ubuthi bayo bufana ne-ethylene, kodwa inokucasuka okunamandla esikhumbeni kanye nolwelwesi lwamafinyila, futhi inomphumela wokubulala izinzwa ekugxilweni okuphezulu. 1,3 I-Butadiene iyavutha futhi ingakha ingxube eqhumayo lapho ixutshwe nomoya; kulula ukuyishisa futhi iqhume lapho ibhekene nokushisa, izinhlansi, amalangabi noma ama-oxidants; uma ihlangabezana nokushisa okuphezulu, ukusabela kwe-polymerization kungase kwenzeke, ukukhulula ukushisa okuningi futhi kubangele ukuphuka kweziqukathi kanye nezingozi zokuqhuma; Isinda kunomoya, ingasakazekela ebangeni elikhulu endaweni ephansi, futhi izobangela ukuqubuka komlilo lapho ihlangana nelangabi elivulekile. I-1,3 butadiene iyashiswa futhi iboliswe ibe yi-carbon monoxide ne-carbon dioxide. Ayincibiliki emanzini, iyancibilika ku-ethanol ne-methanol, futhi incibilika kalula kuzincibilikisi eziningi eziphilayo njenge-acetone, i-ether ne-chloroform. I-1,3 i-Butadiene iyingozi emvelweni futhi ingabangela ukungcola emanzini, inhlabathi kanye nomkhathi. I-1,3 i-Butadiene ingumkhiqizi oyinhloko werabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, i-neoprene) nama-resin ahlukahlukene anezinhlobonhlobo zokusetshenziswa (njenge-ABS resin, i-SBS resin, i-BS resin, i-MBS resin) impahla, i-butadiene nayo inokusetshenziswa okuningi ekukhiqizeni amakhemikhali amahle. I-1,3 butadiene kufanele igcinwe endaweni epholile, nengena umoya ukuze kutholakale amagesi avuthayo. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-halogen, njll., futhi igweme isitoreji esixubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

①Ukukhiqizwa kwerabha yokwenziwa:

I-1,3 i-Butadiene iwumthombo oyinhloko wokukhiqizwa kwerabha yokwenziwa (irabha ye-styrene butadiene, irabha ye-butadiene, irabha ye-nitrile, ne-neoprene)

②Izinto zokusetshenziswa zamakhemikhali eziyisisekelo:

I-Butadiene ingaphinde icutshungulwe ukuze ikhiqize i-hexamethylene diamine ne-caprolactam, ibe enye yezinto zokusetshenziswa ezibalulekile zokulungiswa kwenayiloni.

③Ikhemikhali enhle:

Amakhemikhali amahle enziwe nge-butadiene njengezinto zokusetshenziswa.

Iphakheji evamile:

Sizinikezele ekuphathweni kwekhwalithi eqinile kanye nezinsizakalo zamakhasimende ezicabangelayo, amakhasimende ethu abasebenzi abanokuhlangenwe nakho ngokuvamile atholakalayo ukuze axoxe ngezimfuno zakho futhi aqinisekise ubumnandi obugcwele beklayenti Lokukhetha Okukhulu kwe-China 1,3 igesi ye-butadieneIyathengiswa, Ukubona kuyakholwa! Samukela ngobuqotho amakhasimende amasha aphesheya ukuze abeke ukusebenzelana kwenkampani futhi athembele ekuhlanganiseni izinhlangano kanye namakhasimende akudala asungulwa.
Sithembele ezintweni ezisezingeni eliphezulu, ikhwalithi ephelele, isevisi yamakhasimende enhle kakhulu kanye nenani elincintisanayo ukuze sizuze ukwethenjwa kwamakhasimende amaningi ekhaya naphesheya. Imikhiqizo engu-95% ithunyelwa ezimakethe zaphesheya.
